Galvanizing does help as the aluminum has much less of a reaction with zinc than it does plain steel.
few observations from the trenches.....
Rubber / nylon / snivelon etc washers and attempts at isolation in this manner tend to hold moisture in the joint which is actually worse as water is the third ingredient in the electrolytic corrosion that causes this issue.
Adding SS fasteners to this mix makes it so much worse (especially if you have to remove the fasteners). As a side note I am still not sure what the fascination is with the SS fasteners on the body.......typical conversation here would go like;
customer-"well the frame swap should be a breeze as I swapped all the fasteners to SS with a kit I bought online"
Shop owner-"Awesome.......I just bought a case of cutting wheels"
I have been using a product for a number of years that has performed brilliantly for anti galling / seizing / isolation of dissimilar metals .
This product applied during assembly and after quality paint makes a huge difference. I'm not big on miracle cures but this stuff works very well. I've been testing on my junk which practicly lives in salt water...... never mind the NE road salt........and it really is the shizzle.
